Muscular system

synthetic growth hormones which are natural and do not have any side effects. What I tell to my clients is to increase muscle growth even if they have some problem with their genetics. In most of the cases, this trick works and your body will look muscular easily. Several years back, it worked for me after which I have suggested…

Muscle contraction is a process leading to the shortening and or development of tension in muscle tissue. Tension is developed in muscle tissue when muscles contract. That tension may or may not lead to movement. To contract means to shorten; however, this is not always the case in a muscle contraction. The tension may cause muscle to remain the same, elongate, or condense. When muscles decrease in length (e.x. lifting weights) it is called a concentric contraction. When muscles increase in…

horn syndrome (OHS) being the mildest. Symptoms of Menkes syndrome can be mild or severe. Patients typically fail to meet developmental milestones and tend to have kinky brittle hair, are under weight and experience a deterioration of their nervous system. Other signs include weak muscle tone, sagging facial features, seizures, intellectual delays, low body temperature, pale skin color and weak or brittle bones. As the disease progresses spontaneous movement become noticeably…

Introduction Myasthenia gravis is a neuromuscular autoimmune disorder that affects the skeletal muscles in the body. This disorder is mainly characterized by periods of weakness in the body. The Latin meaning for myasthenia gravis is grave muscle weakness (Lewis 2007). In the United States the prevalence rate is 14 per 100,000 (Lewis 2007) myasthenia gravis can affect any age, but normally it affects people over the age of 50 (Lewis 2007) The mortality rate from myasthenia gravis…

Figure 1 Myosin and actin work together to generate motion within skeletal muscles, however, a vital means of communication, uniting motor neurons and muscles, must be present prior to movement. Tropomyosin and troponin maintain control over the contractions produced by myosin and actin and provide an essential outlet for dictating instructions. Tropomyosin, a two-stranded, alpha-helical coil protein, is positioned laterally along actin filaments and is responsible for “blocking” myosin heads…

There are two sites of muscle fatigue. These two sites include the following: central fatigue and peripheral fatigue. There are five factors that affect muscle fatigue and performance. These five factors include the following: diet, central nervous system function, strength and skill, environment, and energy production (anaerobic sources/aerobic sources).…

One of them was to understand how nerve stimulation endues muscular contraction and to explore this idea we stimulated the sciatic nerve of the subject and we were able to analyze how changes in stimulus intensity and stimulus frequency affected twitch tension of the gastrocnemius muscle. Another goal, was to observe…

The first type of anxiety I felt was trait anxiety. I had never climbed before in my life prior to this class. In addition to having no prior experience with climbing I am scared of heights. I felt anxiety as soon as it was announced that we would be climbing the rock wall. I was very uneasy in the days leading up to our first climb. The second form of anxiety I felt was state anxiety. As soon as I started to climb I felt the feeling of dread rise up within me. When I first started…

ETHICS APPLICATION FORM - Ultrasound imaging of trained and untrained muscles 1. DESCRIBE THE BASIC PURPOSES OF THE PROPOSED RESEARCH. If a person gets paralyzed and cannot move certain muscles, those muscles tend to change structure and get weaker. It would be useful to have a method of seeing what condition the muscle is in order to rehabilitate the person effectively as well as using that method to help clinical diagnosis of ailments known to cause muscle degradation. The basic purpose of…
